Of Epiphytes and Orchids

“They are pigeon orchids!”, Mrs Chee from Education Programmes Division shared with me when I emailed her a picture of some pretty white flowers that I found at our lovely Ecogarden.

pigeon orchid

Things always happen on hindsight. It was only after Mrs Chee told me so, that I realised that yes, they suddenly look orchid-like. Weird how our perspectives can sometimes be blinded until someone comes along and enlighten us!

These pretty white flowers have caught my attention because they were growing off a host plant, the Chinese Fan Palm, so I thought it must be some form of creeper, just like the Morning Glory. Now that I realised what they are, and read more about them, everything starts to make sense.

The reason why the pigeon orchids are growing off another plant, is because they are epiphytes. This means they grows upon another plant non-parasitically. Sometimes, it could be upon some other object. That explains why I thought they are creepers.

I searched further and I found that the pigeon orchid is the most common epiphyte in Singapore, and can be seen on many roadside trees! Now, I am going to be more alert and look out for them on the streets. It seems like they will flower 9 days after a heavy rainstorm, so since it just rained heavily yesterday, we might see them flowering in about more than a week’s time! If you see them, try smelling them too. According to Mrs Chee, they give off a fragrant smell!

An interesting find for me this week. Hope it interests you a bit too!

Lost in Membrane Protein Crystallisation

Exactly a fortnight ago, I found myself in a spot of barney! Now I know that’s an uncanny expression (especially since its cockney slang), but if you’ve watched Ocean’s Eleven, Don Cheadle who incidentally plays Colonel James Rhodes in the movie—Iron Man Three, uses that very expression to communicate that he’s in a spot of bother…

hartmut5So unless we intend to do this job in Reno, we’re in barney… Barney Rubble… Trouble!” remarks a very upset Chad towards the end of the movie clip, referring to the fictional character Barney Rubble in the animated Flintstones television series! Fancy that? Okay, I know I’m digressing but imagine being trapped for nearly two hours in a space with over 100 intellectual 12-17 year olds who seem to know exactly what a German Nobel Laureate was going on about for nearly 2 hours about membrane protein crystallisation! Brain freeze I tell you!

Let me share what I gleaned from the excruciatingly enlightening session on 24 April 2013 by Nobel Laureate, Hartmut Michel. Speaking to an audience comprising mostly secondary, IP and Junior College students, the German genius shared his bio data, the importance of basic science for the progress of mankind and the factors leading to the awarding of Nobel Prizes. He also singlehandedly tackled a whole pile of questions during Q&A on his pet topic, some of which I’ll share in just a bit.

But first… the easy bit.

hartmut6Hartmut’s History
The 65-year-old (disclaimer: by his own admission and against Wikipedia’s records!) Hartmut rose from humble beginnings. His folks had a little home in Southwest Germany. His dad worked in a furniture factory while his mum was employed as a seamstress. The tradition of farming trickled down from his grandparents who were farmers to his immediate family, and so young Hartmut was expected to help tend to the vegetation in their garden.

Since school days ended by the close of morning, the growing child-genius happily strolled through the garden in the afternoon, helping himself to up to four books a week: Archie comic books! I’m kidding! (I just wanted to see if you’d dozed by now!) He said he read books on science, chemistry, geology, anthropology and foreign countries (talk about a unique childhood!). And found in books, an avenue to satiate his curiosity in new knowledge and experiences.

Soon enough, the lad grew up and because he did pretty good in school (as interestingly not all prodigies do), he received a ‘stipend’ (aka a scholarship) from the government and decided to pursue study in biochemistry over geology since less than one percent of geology students found relevant work on graduation, at the time.

Our German genius then rattled away like a runaway chatterbox on the rest of his history, sharing how photosynthesis is the most important process in the world, and how he got his PhD and subsequently the Nobel Prize at the tender age of 40! Over the last quarter of a century, he’s been travelling the world over (lucky geezer!), giving talks about his experiences.

3 ways to get a Nobel Prize
Then our Nobel Laureate touched very briefly on 3 ways to get a nobel prize:

  1. Method development – Hartmut said: “If you have an idea about a method that would revolutionise life sciences, you get to receive a Nobel Prize.”
  2. An unexpected discovery.
  3. If you disprove something which is generally acknowledged.

Profound questions, and profoundly simple answers
hartmut1Following this was where I got the shock of my life. I was surrounded by a company of greatness! Whiz kids all over started raising their hands and asking some pretty profound questions. I was floored. I presume Hartmut was used to these sorts of questions by now, and in any case a number of them were about his work, and so he dished out some pretty down-to-earth answers, which most of us present found, quite refreshing and amusing! I’ll just list a few of the interesting questions and answers that made an impression on me, but I’ll list the rest of the questions below and you can leave behind a comment if you’d like to know Hartmut’s answers to the rest of the questions or to a particular question.

  1. What principles of life have you followed to get to where you are?
    • You have to be energetic, motivated, interested, have clever ideas (which takes time) and work hard.
    • You have to be at the right place at the right time.
    • A broad education is better than a narrow education.
    • I have never followed a master plan but have learnt to be flexible.
  2. Do you need to know everything in order to make a discovery?
    • You cannot know everything. You must have a feeling of what is important and what is not important.
  3. How did you decide on your area of study?
    • The study of membrane proteins is very interesting. So, I chose that and tried to understand how membrane proteins work, how photosynthesis works. I researched respiration, how the body produces water. Some 900 different receptors control different things like our blood pressure. And you can take meds to activate or deactivate different receptors depending on the disease one may have.hartmut4

Some of the other questions asked at the seminar were: Did you encounter any difficulty sustaining all of your interests or did you have to sacrifice some interests? What kept you going for 3 years to persevere in your discovery? What is epigenetics and one of its associated moral issues? What would you choose to be, other than a scientist? Who helped in your experiments?

hartmut3What were the hardships in your research journey? Who has cut an inspirational figure for you? Are there any other reasons you chose biochemistry instead of physics of geology, other than better career prospects? When you have many options, which one do you choose? How do you get over differences in opinion with your research counterparts? How does one choose a research partner? Is there any difference in the research produced in Germany versus the research done in Singapore?

My Learning Points
Nearing the end of the Q&A, my head was just about swirling with the frenzy of questions and bullet-answers. There wasn’t even time to orbit to cyberspace! I was crystallised in membrane protein discussion! Oh well… thanks to the 65-year-old German and his captive audience, today I’m better for it. How so? Well, anyone can cut it big, no matter what you’re background is. And in time, people will reward and recognise your efforts even if you think no one’s watching. : ) 

Hartmut Michel moved to the Max Planck Institute for Biochemistry decades ago and succeeded in crystallizing the photosynthetic reaction centre of purple bacteria, a membrane protein complex, which had been considered to be impossible at the time. Together with Johann Deisenhofer, he was then able to determine its structure by X-ray diffraction. For this work, Deisenhofer, Huber and Hartmut received the Nobel Prize of Chemistry in 1988.

What the chindogu!

The Japanese ruled the innovation roost back in the day! Remember how revolutionary the Sony walkman, discman and mini-disc player were? Man, those products created quite a stir, kinda like these inventions below—only, they were a lot more revolutionary (with the exception of the awesome banana travel case of course!)

SONY DSC

 

 

 

Check out a whole stack of very unusual Japanese inventions at Science Centre’s quirkiest exhibition called… Quirky!  There are even a number of interactive exhibits to immerse yourself in!

 

 

 

 

Here’s one that I had a bit of fun with! It’s aptly called… the Hapi Drum! You really should try it! Because it works! : )))

 

 

Don’t miss it. It’s all happening on level 2 at the only Centre that brings you all kinds of experiences, including a walk down the quirky side of science!

Mosquitoes and Dengue in Singapore

Last week, Radio 938Live asked me for an interview on mosquitoes and dengue. The interview that went on air was of course much shorter than the chat I’d had with the radio man, so here’s a more extensive Q&A:

Does the weather have to do with the increase in mosquito numbers in Singapore?

The weather probably does have some impact on mosquito populations, although I think we still don’t really know to what extent that is the case. Rainfall will increase the number of containers with water, which are potential breeding sites for the mosquitoes, but lots of rain can also wash away larvae in puddles and drains. The temperature will have some impact on how fast the mosquitoes develop, and therefore how fast the population grows. But there are many other factors that also affect mosquito populations – including NEA and the Mozzie Wipe-out – so conclusively pinning down any fluctuations on the weather is very difficult. Some mathematical modelling studies have been able to link temperature to dengue incidence, but what role mosquito densities play in this is not clear.

What causes a mosquito epidemic?

We have to separate a growth in mosquito population from a dengue epidemic here, and the two are not necessarily related. It is possible to have a dengue cluster or epidemic with relatively few mosquitoes. This is further complicated by the fact that measuring mosquito densities can be very tricky. If we read in the papers that the number of households found to have mosquitoes breeding has increased, that could be either because there are more mosquitoes or because the NEA is checking more households. The NEA is monitoring mosquito populations with ovitraps and gravitraps, but these have their limitations too.

You studied aspects if the Aedes aegypti and Ae. albopictus, vectors of the dengue virus. What can you tell us about their unique behaviour as compared to “normal” mosquitoes?

They are normal mosquitoes! If you mean whether dengue-infected Aedes mosquitoes behave differently from healthy Aedes mosquitoes, I couldn’t tell, because we didn’t have any infective insects in our lab, and I’m not aware of anyone else studying that. If you mean whether these two Aedes species are different from other species, then there are many differences. They prefer to lay their eggs in different kinds of water bodies, they bite at different times of the day, you tend to find them in different areas etc.

In your time with the National Environment Agency, what have you learnt about this type of mosquitoes and how to control them?

Most of what my colleagues and I were studying was related to what the mosquitoes are attracted to, so we could trap them more effectively, and how they behave towards the traps we were designing. We designed a gravitrap, which to a female mosquito wanting to lay eggs looks and smells like a perfect breeding site, but is actually a lethal trap for both her and any of the eggs she managed to lay before being trapped. While some people were hoping to use this as a new weapon to control mosquitoes, it was actually meant as a monitoring tool, an improvement on the ovitraps that are being used routinely but can turn into breeding sources themselves if not maintained properly.

What can Singaporeans do to support the fight against the spread of dengue and the Aedes mosquito?

Follow the advice of NEA and prevent mosquito breeding wherever you can. This has been the same message for decades, and it is actually working – we have a lot fewer mosquitoes in Singapore than other places with similar conditions. The problem is that the few that are remaining are still enough to allow dengue to spread. And reducing a relatively low mosquito population even further is so much more difficult. So public education is important, to try and make everyone understand the need to look out for potential breeding sources, and that every household’s effort does make a difference. NEA is always finding new ways to put out that message, and we here at the Science Centre are doing our bit, too. We have a section on dengue in our Living with Viruses exhibition, as well as SARS, HFMD and more. And the Megabugs Return! exhibition that opens this weekend has a huge, moving Aedes albopictus with some info on these mosquitoes and dengue, too.

Earth Hour – What is your personal report card?

March and April tends to set most of us thinking more about Mother Earth, in view of all the rave about Earth Hour and Earth Day. Like what I mentioned in my earlier blogs (Earth Hour – What does it mean to you?) and (Reflection over the Earth Day), these are just symbolic events while the day-to-day actions are more meaningful and useful. Hence, it is great when campaigns also calls for going beyond the “Hour” and more lasting action.

Some say that conservation efforts are already too late to remedy the harm that has been done. I say not all is lost yet. Every single efforts will help to delay the climate change process and in time to come, the upstream efforts will reap results downstream, if there is concerted effort.

Personally, I take all these sudden interest and discussion about conservation as a reminder to my own actions. I remind myself that simple steps on a daily basis will contribute to conservation in the long run, to shut down the laptop at the end of the day, to switch off the power supply to all electrical appliances when they are not in use, etc. I am glad that I have slowly turned this into a habit. The key is to take small steps.

You probably already knew that appliances draw energy from power sockets even when they are left on stand-by.

This is the Power Aware Cord of the Climate Change exhibition (Science Centre Singapore).  The power aware cord glows when appliances are left on stand-by. It glows brighter as an energy intensive appliance draws more energy.

Simple actions matter too. Share this to remind your friends and family how they can conserve energy by switching off their electrical appliances when not in use!

A little bit of chicky-ness

Do you know that there is a live animal exhibits in the Science Centre Singapore? I always enjoy peeking at the little animals when I pass by the area, and check on what they were doing.

From mice to gerbils to hedgehogs, they never fail to amuse me, even when they were asleep.

More than meets the eyes

Yen is a Marketing professional at Science Centre Singapore.

My own favourite corner of the entire Science Centre Singapore is definitely the Mind’s Eye. Because to me, the eyes don’t see everything. Even if they do, our mind may not interpret everything correctly. And then again, the world is how we made it out to be so one scene/image can be perceived differently by different individuals.

The Minds’ Eye exhibition is located near the entrance to Science Centre, right after the turnstiles. Perhaps it’s for the best since this might be where you need real ‘eye power’.  Here, the exhibits can be broadly categorised into: (click on the images to view larger versions)

1Impossible objects
Objects or scenes which do not exist or is geometrically impossible. This can be done with shading, which can cause something to appear farther away, or the careful use of lines, which can give depth or dimension to an object. Such as the famous still life painting below (top, left photo) by Jos De Mey, who incorporated an impossible cube – can you spot the cube?


2
Ambiguous illusions
Ambiguous images are optical illusions that exploit graphical similarities and other properties of visual system interpretation between two or more distinct image forms. Such as the exhibit on the right – do you see the pillars or the men, or both?

3

Anomalous Motion
Some paintings enable viewers to see motion within them!  This perceived motion is a complex illusion that depends on colour, contrast, and peripheral vision, which is what you see from the ‘corners’ of your eyes. One example is the exhibit on your left.
 

4Distortion arts/ Anamorphosis
Anamorphosis is a distorted projection or perspective requiring the viewer to use special devices or occupy a specific vantage point to reconstitute the image. You can see this big exhibit near the entrance of Science Centre (see right image). This is a painting of a mysterious island with a cylindrical mirror placed where a circular sun was painted. Through the cylindrical mirror one can see the image of France author, Jules Verne.

5

Left is an image of another interesting painting I found. Typically one will see both a pile of books and a librarian’s face. However, according to the exhibit explanation, stroke patients who lost their ability to recognise faces can only perceive the books in this painting, but not the face of the librarian!

Just like the topic it covers, The Mind’s Eyes exhibition has more going on there than meets the eye. The estimated time required to complete this gallery is stated as 15 – 30mins but I think the curious few should prepare to spend one whole morning/afternoon here. Because this exhibition is not restricted to the entrance area only – the two stairways near the Atrium of Science Centre are actually filled with more paintings and images on all these optical illusions! Thus you can climb both staircases to third floor and challenge yourself on what you see and how these illusions come about. Think also, of the history behind these and the future importance of what you can, or cannot, see. Be prepared to be enlightened, or even be inspired, from this mind-boggling exhibition.

Taking Science Outside The Classroom

Many students when asked about their perception of science often associate it with “Formulae”, “Equations”, “Exams”, “Experiments”, “Chemistry / Biology / Physics”. Undoubtedly, many of you would have probably thought the same if you were asked the question. I lament the fact that the excitement that comes with science being fun is clearly missing in these responses.

We are, by nature, curious. From a young age, we begin to wonder and question how the world around us works. We discover some of these workings by accident or observation, and others, we are taught in school. We learn about new discoveries being made on the news and often we have the opportunity to carry out laboratory experiments in schools to find why something works the way it does. Yet, at the end of the day, the focus for many students lie on how many marks they receive on their end of year science examinations.

Science is more than just textbooks and exams. Our learning of science does not start and end in school; it is a process that can last a lifetime and is all around us, applicable to the most basic of tasks, like brushing one’s teeth in the morning. Learning science does not need to be dreary, as many students perceive it; science can be fun, rewarding, and entertaining if done right.

SSFWith that in mind, I invite you to come and discover how much fun science can be at this year’s Singapore Science Festival 2013, jointly organised by the Agency for Science, Technology & Research (A*STAR) and the Science Centre Singapore. Held over a period of two weeks, from July 19 to August 4, this year’s science festival promises a range of hands-on events that will show you how science works in a fun, entertaining way away from the typical classroom set-up. Here are some of the exciting highlights we have lined up this year:

The “Dancing Scientist” (19 July – 21 July)
22-year old Jeffrey Vinokur, famously known as the “Dancing Scientist” across the world, will be conducting a series of fun, hands-on science experiments for kids, students, and families at the three day science carnival, X-periment!

Megabugs (20 April – 18 August)
An attraction for visitors of all ages, Megabugs is a 4-month (April – August) long exhibition displaying an army of gigantic-sized insects. Just think what would happen if these insects were alive!

Singapore Mini Maker Faire (27 July – 28 July)
If you have always wanted to put on your ‘mad scientist’ goggles and invent something extraordinary, a good place to start looking for inspiration is at this showcase of do-it-yourself projects from local and international inventors.

STAR Lectures (29 July – 31 July)
Partnering with the Royal Institution of Great Britain, the STAR lectures will unveil the chemistry of the world around us by looking at the three basic elements found our planet and without which life is unsustainable – Air, Water, and Earth.

Living In The Ocean Sleepover Programme – Dolphin Tales Under The Stars (2 August – 3 August)
Learn more about dolphins, the way they live, behave, and communicate in this overnight event at the Dolphin Lagoon in Sentosa. You will also have the opportunity to encounter the pink dolphins up close.

I hope by attending the Singapore Science Festival this year, you will see how fun and enjoyable Science can be and you will continue your pursuit in discovering how the world works around us.

35 Years of Science Centre Singapore

35th Anniversary of SCSAs the Science Centre Singapore celebrates its 35th year, we look back with fond memories and count the blessing of having inspired generations of Singaporeans and guests through the engaging world of science. Together with the Omni-Theatre and Snow City, the Centre has seen almost 30 million visitors walk through its doors since the first foundation stone was laid in 1977.

Like Science, the Centre is constantly evolving – creating and presenting innovative ways to spark interest and ignite curiosity in science. The Centre has also become a preferred partner for collaborations and we have grown and deepened our alliances with local and international agencies in the business of promoting science and technology.

As part of our 35th Anniversary celebratory events, we can look forward to an expanded Singapore Science Festival with more international participation; a unique competition called ‘Science is Everywhere, Everyday’ to capture scientific phenomena all around Singapore; a made in Singapore blockbuster exhibition entitled ‘Megabugs Return’ and a special gallery on Wallace’s exploration in South East Asia to mark his 100th death anniversary.

At this significant milestone, we take stock of our strengths and weaknesses to rethink and reinvent for the future. We continue to seek new partners and sponsors to aid us in developing new attractions to enrich the Science Centre experience. We have lined up plans to build a Digital Planetarium, Virtual Interactive Aquarium and a Children Science Centre.

The Centre has also earned a reputation as a leading edutainment institution in the region. We will continue to provide consultancy services and bring our innovative Science Shows and travelling exhibitions that have run successfully in Bangkok, Jakarta and Beijing, to the region.

I would like to thank the public agencies, private companies and the Science Centre team for their support, enabling us to excite, educate and inspire, and transform the minds of millions through discovering the beauty in science. I look forward to working closely with our partners and the team to make the next quantum leap in science edutainment with an aspiration to become not just among the best in the industry but also a thought leaders in science communication, promotion and engagement.
